Hi suraiya,
Firstly we would say that stay positive and such anxieties are common during exam preparation
time. Juggling between work and studies is tough so you need to define a significant time for your
GMAT preparation. Sometimes taking few days off work for preparing for the GMAT can help a person tremendously. If you have time this may not be a bad idea. Take practise GMAT tests to see how you are doing. If you cannot do that don't worry. What might work instead is to set aside 1-2 hours at night on weekdays and major part of your weekend to study and prepare for GMAT in this case we will suggest a good 2-3 months preparation. However we recommend you to keep taking practice tests to gauge your performance. Since you know your weak areas you can focus on them accordingly. You might be able to study more than the given hours and maybe able to handle it in 6 weeks. It all depends on your potential really.
There are various ways you can use to practise for your GMAT. You might need to change your
practise style and try this combination to provide you flexibility and different styles to practise so it doesn't get monotonous.
It could be combination of-
1-Books- Books like- The Official Guide for GMAT Review, The Official Guide for GMAT Verbal
Review, The Official Guide for GMAT Quantitative Review etc could be used.
2-Online Study Guide: Websites like Knewton, Grockit etc provide you with practise questions
online.
3-Smart phone applications- Kaplan, Veritas etc offer applications to prepare for GMAT on your
smart phones
